Overview
Commercial readiness
Confirm contribution margin after platform fees, promotions, and logistics; localized product pages; an inventory or fulfillment plan; and a named customer-service owner in the target language.
Channel and measurement
Choose the primary marketplace and search channel for the target market, define one conversion per channel, and set the measurement window before committing budget to competitive, high-CPC categories.
